Conditions for Setting the DTC

B0091 01 

The inflatable restraint sensing and diagnostic module has detected the center front impact sensor has been shorted to voltage

B0091 02

• The inflatable restraint sensing and diagnostic module has detected the center front impact sensor has been shorted to ground.
• The center front impact sensor current is greater than 23 mA for greater than 5 milliseconds.

B0091 04

• The inflatable restraint sensing and diagnostic module has detected an open/high resistance in the center front impact sensor.
• The inflatable restraint sensing and diagnostic module has not received a message from the center front impact sensor for greater than 375 milliseconds.

B0091 05 and B0091 0C

• The inflatable restraint sensing and diagnostic module has detected the center front impact sensor has been shorted to voltage.
• The inflatable restraint sensing and diagnostic module has detected an open/high resistance in the center front impact sensor.
• The inflatable restraint sensing and diagnostic module has not received a message from the center front impact sensor for greater than 375 milliseconds.

B0091 39

• The inflatable restraint sensing and diagnostic module has received a Not OK (NOK) message from the center front impact sensor.
• The inflatable restraint sensing and diagnostic module has not received a message.

B0091 3A

• The inflatable restraint sensing and diagnostic module has received identification message from the center front impact sensor which does not match the identification stored in the inflatable restraint sensing and diagnostic module memory.
